Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
We’ve checked your page and we can see that Rank Math added the correct meta title:

You can also check it by using https://rankmath.com/tools/meta-tag-analyzer/ and https://www.heymeta.com/
However, if Google is not showing the correct meta title then please note that nowadays, Google does that very commonly. Even when everything is fine, Google may choose to display a different meta title for your search query result. Google may skip the custom meta data you have set and instead display something from the page’s content that better matches the search intent.
You can follow this URL for details on this issue:

Hope that helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
